Antibiotic choice

Before prescribing antibiotics physicians examine patients and determine their exact symptoms to identify the condition. Only bacterial infections should be treated with antibiotics. For some minor cases the use of antibiotics on the first stages is not recommended. Still if the condition deteriorates, the use of antibiotics is needed.

When the diagnosis is made a doctor prescribes an antibiotic correct for each individual case. Sometimes the application of antibiotic can be corrected or the other antibiotic is recommended.

A culture can be taken to understand if bacteria are causing the infection. In more serious cases when hospitalization is needed, special test on susceptibility of bacteria to antibiotics is taken.

Some types of antibiotic drugs are useful for the particular bacteria. If the cause of the infection is unclear, but suspected to be due to bacteria, the physician can suggest using stronger wide-spectrum antibiotic to suppress a large variety of bacteria.

Women can be more prone to antibiotic actions because they kill or suppress normal bacteria in the vagina. So, vaginal yeast infections can start developing after antibiotic treatment. Women often experience burning during urination, vaginal discharge and other symptoms of yeast infection. Doctors often recommend women during the treatment with antibiotics to use other medications or soon after the treatment with antibiotic drug to use antifungal medication.

Women should also remember that antibiotics can make birth control pills ineffective.

Pregnant women should not use antibiotics without first consulting a doctor. Some antibiotics can be very dangerous for the unborn baby.

If your doctor prescribes you Levofloxacin, you should know that there is a low possibility of bacteria to resist to this antibiotic. It is very effective and produces expanded gram-positive spectrum of activity.

Levofloxacin appears to be active against anaerobes, has a great effectiveness against lower respiratory tract pathogens.

Doctors often prescribe Levofloxacin for the treatment of nosocomial pneumonia. Besides, the medicine is effective against atypical respiratory pathogens such as Legionella pneumophila, Mycoplasma pneumoniae, Chlamydophila pneumoniae and resistant pneumococci.

Levofloxacin is often the drug of choice for patients with liver disease who are contraindicated to use other types of antibiotics.

The medicine does not interact with alcohol. Still its use with alcohol is not recommended.

If you start using this antibiotic you should be watchful for some of its possible side effects. It can increase the risk of tendon ruptures and postpone the healing of fractures especially in people of older age or taking corticosteroids.

Some people may experience arrhythmia and prolongation of the QT interval during use of Levofloxacin.

Patients with diabetes should control the level of blood sugar during the treatment with this antibiotic as it may increase the risk of dysglycemia.

Antibiotics

Antibiotics are the medical tools used to treat and prevent various kinds of bacterial disorders from mild to severe ones. The use of antibiotics should be carefully considered in each individual case. The unwise use of antibiotics often leads to side effects, development of bacterial resistance to certain kinds of antibiotics and numerous health consequences.

The fact is not all antibiotics work for all kinds of microorganisms which provoke inflammation and disease in a human body. Antibiotics can be divided into groups of narrow spectrum and wide spectrum medicines. From the very name narrow spectrum are administered only for certain types of bacteria and are not effective for all the others.

Broad spectrum agents work against many types of bacteria and are used to treat various bacterial infections. The use of a particular type of antibiotic is based on the condition which a person suffers from, his personal history of allergic reactions to antibiotic agents, tolerability and response to the therapy. Besides, certain groups of patients such as pregnant women or children or people with chronic or acute kidney or liver disorders cannot use antibiotics or should be adjusted the alternative safe types of antibiotic agents.

As narrow spectrum antibiotics are only effective against a limited range of microorganisms, they are used for certain uncommon types of bacterial infections or infections of very serious character. They kill only bacteria which cause the disease. While broad spectrum antibiotics are often self-administered for a great number of infections from common sore throat to infections of the urinary tract. They kill every pathogen they meet on their way.

Certain groups of antibiotics target the infections of certain body organs and systems. For instance, bacterial infections of the gastrointestinal tract and upper respiratory tract can be treated by different antibiotics.

There is another division of all antibiotics to bactericidal and bacteriostatic.

Bactericidal antibiotics have a direct purpose to kill the bacteria in the human body. This type of antibiotics may injure the membranes of pathogens or destroy the DNA and RNA of bacteria.

Bacteriostatic antibiotics don’t allow bacteria growing in the body. The pathogens don’t die, but they can’t grow or replicate either. Then the immune system starts its work to get rid of these pathogenic bacteria. For instance, some antibiotics prevent the growth of bacteria by interfering in the process of protein formation and thus stop bacteria from developing. Lots of bacteriostatic antibiotics impair the ability of bacteria to replicate by depriving bacteria from important metabolites for making new DNA and RNA.

Levofloxacin origin and approved uses

Levofloxacin is a generic name of the antibiotic agent which comes in the formulation of many branded medicines such as Levaquin, Leva-Pak, Tavanic, Levoday, Cravit and others. The medicine belongs to the 3rd generation class of fluoroquinolones and is approved for use by the FDA.

Actually the medicine was discovered by one of the Japanese pharmacological companies. The purpose of this antibiotic was to ensure the excellent antibacterial potency of the medicine and decrease the toxicity for the body.

Today Levofloxacin can be found in all the parts of the world and used for various infectious diseases.

U.S. FDA approved this medicine for a variety of infectious diseases in their acute state or chronically ongoing.

In the list of approval uses there are:

Acute bacterial sinusitis

Acute bacterial exacerbation of chronic bronchitis

Nosocomial pneumonia

Community-acquired pneumonia

Complicated skin and skin structure infections

Uncomplicated skin and skin structure infections (mild to moderate) including abscesses, cellulitis, furuncles, impetigo, pyoderma, wound infections

Chronic bacterial prostatitis

Complicated urinary tract infections (mild to moderate)

Acute pyelonephritis (mild to moderate)

Uncomplicated urinary tract infections

Inhalational anthrax

Off-label uses (not approved by the FDA) include:

Helicobacter Pylori eradication

Pelvic inflammatory disease (PID)

Gynecological infections

Enterocolitis (Shigella)

Epididymitis (non-gonococcal)

Legionnaires disease

Peritonitis

Tuberculosis

Community-acquired pneumonia in children

Typhoid fever

Endocarditis

Levofloxacin can be considered one of the well-known medicines with proven effectiveness. The long years of its use have shown its advantages and weak sides.

Advantages of the medicine include its convenient and easy use. The dose is taken only once a day which excludes the missing or skipping doses. This is of course one of the benefits for patients who often forget about taking several doses of the medicine per day.

The other advantage of the medicine is its high effectiveness against broad spectrum of susceptible bacteria. It is bactericidal for many existing types of bacteria with fast onset of action.

Patients using this antibiotic rarely complain about side effects of this medicine. It is safe and well-tolerated by most patients. In comparison with other medicines from the same drug class of fluoroquinolones, Levofloxacin does not impose the risks of any cardiovascular effects, central nervous system disturbances and phototoxicity.

As the medicine has no P-450 metabolism, it does not significantly interact with other medicines.

Levofloxacin shows greater gram-positive spectrum of activity against Streptococcus pneumoniae than other fluoroquinolones.

Excellent bioavailability both orally and intravenously makes Levofloxacin a drug of choice for many bacterial disorders demanding extra strength and extra amounts of the active components.

Main disadvantages of the medicine involve the risks of certain side effects particularly risk of peripheral neuropathy, prolongation of QT, risks of tendon ruptures.

Important things to consider when buy Levofloxacin

tabletsThe right course of antibiotic therapy means that the antibiotic is chosen correctly and no pills are left in the pack after the treatment is completed. So with antibiotics it is very important to finish the treatment even if the positive result is observed in the first days of taking pills.

This antibiotic has a potential of risk to cause swelling and even rupture of a tendon (flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone). The tendons of the heels are more prone to this risk.

The risk of rupture exists even after the treatment is stopped. So, people with tendon or tissue problems, people over 60 years of age or those who take steroids should inform their doctors before buy Levofloxacin.

How to prevent resistance to antibiotics?

bacteriaBeing careful while having the treatment with antibiotics can prevent resistance of bacteria and dangers to health. One should consider the following things before using any type of antibiotic.
